TRANSCRIPT
VOLT AMP
The TPA3116/18 class D amplifier IC is a leap in terms of audio quality.
Our board is a high quality implementation of the stock design.
Ÿ Using TPA3118 (better grounding of main IC)
Ÿ Anti-Pop circuit
Ÿ Bootstrap snubber mod
Ÿ Brand name components as per picture
Ÿ Radio avoidance switch (to reduce interference)
Ÿ PCB with extra copper (since on transient’s current can spike to 5A)
Note that PCB comes in 2 flavors:
1. Volt is a shield and beneath it has connector that will plug into our DACs
(Piano 1.1 and Piano 2.1). It has no RCA inputs. (Capacitance Multiplier can
be added as a standalone board).
2. Volt+ is a standalone amplifier with RCA IN (stereo). In addition to
everything that the Volt has, we have added a circuit in the power supply
that will reject spikes and noise to about 60db. The name of the circuit is
"Capacitance Multiplier". Please note that Class D amplifier needs a quiet
PSU.
Volt + can be used with our DACs through the RCA input, as a standalone
board.
